Light Sensor NaPiCa Technical Terminology

Term Symbol Explanation
Reverse voltage VR The applied voltage between the cathode and anode.
Photocurrent IL The current that flows between the cathode and anode when light is applied.
Power dissipation P The electric power loss that occurs between the cathode and anode.
Operating temperature Topr The workable ambient temperature range at which normal operation is possible under the condition of a prescribed allowable loss.
Storage temperature Tstg The ambient temperature range at which the sensor can be left or stored without applying voltage.
Peak sensitivity wavelength lambdap The wavelength of light at which sensitivity is at its maximum.
Dark current ID The current between the cathode and anode when reverse voltage is applied during darkness.
Rise time tr Time required for the output waveform to rise from 10% to 90% when light is applied.
Fall time tf Time required for the output waveform to fall from 90% to 10% when light is cut.
